After successfully implementing post-tensioned slabs in our apartment buildings at The Botanic Silverdale, we’re now bringing the same innovation to our Stage 8 duplex villas!
By enhancing structural integrity and material efficiency, post-tensioning allows for more efficient slab to slab thicknesses, longer spans, and faster construction—a key advantage in large-scale developments.
The process begins with high-strength steel tendons placed strategically within the slab before the concrete is poured. Once the concrete reaches the necessary strength, hydraulic jacks apply tension to these tendons, introducing compressive forces that counteract tensile stresses. This significantly reduces cracking and deflection. The tendons are then anchored in place and, in bonded systems, grouted for added durability.
With this method, construction timelines are shortened, less secondary structure is required, and buildings achieve greater strength and longevity – It also result in a significant positive impact acoustically for multi-unit developments. We think this is a game-changer for our construction projects.
